My invention relates to gas heaters .and the like and the purpose of my invention is the provision of a gas heater in which the radiants thereof are associated with the fire- Vbox of the heater to produce a flue at the rear of the radiants through which air is free to circulate thus preventing loss of heat from rearward circulation and supplying additional air to promote perfect co1nbustion and to insure the proper discharge ofthe products of combustion from the heater.

It is also a purpose of my invention to provide a gas heater having radiants formed interiorly with passages or flues in communication at their lower ends with the nozzles of a. burner so that the fiames emanating therefrom are directly received in the flues, and in communication at their upper ends with a common discharge channel through which unburned gases and other products of combustion are delivered to outlet flue.

I will describe only one form of gas heater embodying'my invention and will then point out the novel features thereof in claims.

In the accompanying drawings Figure 1 is a View showing in front elevation one form of gas heater embodying my invention with a portion of the frame of the heater being broken away.

Figure 2 is a horizontal sect-ional view taken on the line 2-2 of Figure 1.

Figure 3 is a vertical sectional view taken on the line 3--3 of Figure 1.

Referring specifically to the drawings, in which similar reference characters refer to vsimilar parts in each of the drawings, my invention in its present embodiment com-v prises a frame which in the present instance is of rectangular outline and includes a bottom wall provided with a longitudinally extending slot 16, an upper wall 17 having a. slot 18, and a rear wall 19 inclined rearwardly and downwardly as' clearly shown in Figure 3 so that the lower edge is spaced from the rear edge of the bottom wall 15 by the slot 16. Adjacent the lower edge and on the front side of the rear wall 19 are forwardly extending projections 20 arranged at spaced intervals along the length of the frame, while above the projections 20 is an- Jther projection 21 which latter is in the form of a continuous rib extending horizontally from one end of the rear wall to the other. These projections 20 and 21 co-operatein maintaining radiants R in spaced relation to the rear wail 19 in order to provide therebetween` ra Vvertical flue 22 for a purpose which will be described hereinafter. Above the rib 21 the forward side of the rear .wall 19 is recessed tol form a longitudinally extending channel 23 increasing` in depth from the opposite ends. thereof yto the center where an outlet opening. 24 is provided.

In the present embodimentV of my invention l have shown the frame constructed so as toy be accommodated in a suitable wall pocket 25, ears 26 being formed on the frame for attaching thelatter to the walls of the poclret'so that the frame is supported inthe elevated position shown in Figure 3. VAn

outlet pipe 27 extends into the outlet opening 24 and constitutes a discharge flue through which the products of combustion may be conducted to a chimney (not shown) as will be understood. y'

A burner designated generally at B is supported from the rear wall 19 by means of bolts 28 extending through the opposite ends of the Vburnerrbody andthrough flanges on the wall 19 all as clearly sho-wn inFigure 1, with spacing sleeves 29 surrounding the bolts toV maintain the burner in dehnite spaced relation to the lower edge ofthe rear wall 19 so that the nozzles 30 of the 'burner will extend upwardly into the slot 16. The specific construction of the burner will not be described herein as it forms the subject inatterV of a separate application. Gas is adapted to be supplied to the burner through a pipe 31 controlled by avalve 32.

As clearly shown in Figure 3, each radiant R is supported at its forward lower edge upon the bottom wall-15 and is constructed to provide ya vertical passage or flue 33, the lower end of which is .open andL disposed directly above thecorresponding group of burner nozzles 30 so that the flames emanating therefrom can pass upwardly of the flue.

ill)

operating to heat the radiante thus causing a forward and horizontalradiation of heat, with the burnt gases being carried off through the openings Btand ultimately into the pipe 27. l/Vith the burner in operation, air is caused to circulate upwardly of the flue 22 to prevent radiation of heat rearwardly of the radiants and to vcombine with the burnt gases on reaching the channel 23 so as to insure the proper discharge of the burntgases from the hea-ter into the pipe 27 The supply of air to the channel through therflue A22 also functions to promote perfeet combustion so that maximum heating eiciency is obtained.

Although I have herein shown and described only one form of gas heaters embodying my invention, it is to be understood that Vvarious changes and modifications may be made therein without departing from the spirit of the invention yand the spirit and scope of the appended claims,

What I claim is l. A gas vheater comprising a frameof substantially rectangular form in outline having slotted upper and lower walls and al hack wall formed with projections on'its front side and recessed at `the topy to form a horizontally disposed channel, an outlet opening in the back wall within the channel, radiants supported ,atk their forward lower edges on the lower wall and having lips at their upper lends engaging within the .slot of the upper wall, and a burner having nozzles and discharging flames through the slot in the lower wall into the radiante, said radiants havingilues extending upwardlyfrom said. slot and provided with lateral outlets effecting connnunication between the ues and said channel.

2. A gas heater as embodied in claim l wherein the channel increases in depth from the opposite ends thereof1 to saidoutlet opening. Y Y

3. In a gas heater, a frame having a slotted bottoni wall, and a rear wall formed with projections on the front. side thereof adapted to maintain radiants supported on the 'bot-Y tom wall in spaced relation'to the rear wall to provide an air flue therebetween, said rear wall adjacent its top being formed with an outlet opening and a channel increasing yin depth .toward the opening and arranged to receive burnt gases from said radiants.

4. In a gas heater, a frame having a slot- 5. A gas heater comprising a frame having slotted upper and lower walls, and a back wall inclined rearwardly from the top wall and formed on its forward side with projections and a .recess at the top extending khorizontally tor form a channel, an outlet `opening in the back wallk inedially ofi-the channel with thelatter increasing in depth from its ends toward said opening, radiants supported at the forward lower edges on the lower walland having lips at their upper ends engaging within the slot of the upper wall, and a burner iaving nozzles for lisnchargino` flames upwardly through the slot in the ower walland upwardly into the radiante, said radiants having iclues extendupwardly from said slot and provided with lateral outlets for discharging burnt gasesinto said channel, said projections serving to maintain the radiante in spaced relation to the rear wall to provide an air flue between the two which is in communication at its upper end with said channel.

6.. In a gasheater, a frame havingV a slotted bottom wall, and a rear call formed with projections-on the front side thereof, radiante supported at .their lower forward edges on the lower wall .and adapted to be' arranged in spaced relation to the rear wall by the projections, to providelan air due, with rear wall adjacent its top being form-ed with a longitudinal channel and an outlet opening and the flue being open at its lower end and having its opposite end coin-nnmicating with the channel` 7.. In a gas heater, a frame having Va slotted bottom wall and a rear wall formed with transverse projections, radiants supported in spaced relation to the rear wall by the projections and forming an air flue therebetween, the rear wall adjacent the top being formed with an outlet openino` and a channel increasing in depth toward the opening and adapted to receive gases .from the radlants and the air fine being openy at its lower end and having its opposite end communicating withthe channel.
